If you want to create a permalink in WordPress to all entries on a particular day, it’s pretty simple:

<?php echo mysql2date('Y/m/d', $post->post_date); ?>

For me, I put http://ijsm.org/archives/[echo statement] in an anchor I’ve placed this around my instance of the_date to get a permalink that has the date. I suggest adding a title=”Permalink to entries on this date” to the anchor element in an effort to make it clear to your readers what you are doing.
